Problems solved by technology

[0003] The traditional ion-conducting layer in an electrochromic device is generally a solid electrolyte. However, this type of electrolyte needs to be continuously applied with a high voltage to complete coloring or fading, and it takes a long time for coloring or fading, which hinders the electrochromic device. Application of color changing device

Abstract

The invention provides an electrochromism device which comprises a first transparent substrate and a second transparent substrate which are relatively arranged, wherein a first transparent conductive layer and an electrochromism layer are formed on the internal surface of the first transparent substrate; the first transparent conductive layer is arranged between the first transparent substrate and the electrochromism layer; a second transparent conductive layer and an assistant electrochromism layer are formed on the internal surface of the second transparent substrate; the second transparent conductive layer is arranged between the second transparent substrate and the assistant electrochromism layer; adhering layers are arranged on peripheral edges of the electrochromism layer and the assistant electrochromism layer; the electrochromism layer, the assistant electrochromism layer and the adhering layers enclose a cavity in which an ion conducting layer is arranged, wherein the ion conducting layer is in a form of gel. The invention also provides a preparation method of the electrochromism device. According to the electrochromism device, the ion conducting layer is in the form of the gel, so coloring or discoloring can be carried out by exerting a relatively low voltage; shorter time is used; and high stability is ensured.

Description

technical field [0001] The invention belongs to the field of electrochromism, and in particular relates to an electrochromic device and a preparation method thereof. Background technique [0002] Electrochromic materials refer to materials whose optical properties change due to an applied electric potential, which can be used to produce electrochromic devices that change the transmission or reflection of electromagnetic radiation by applying an electric potential. Electrochromic devices can be used in many fields at present, such as: vehicle inlaid glass (such as car windows, skylights), building inlaid glass, display devices, optical components, mirror bodies and shields for electromagnetic wave irradiation, etc., its function is to be able to Effectively block the interference of external light or heat, and better protect privacy. [0003] The traditional ion-conducting layer in an electrochromic device is generally a solid electrolyte. However, this type of electrolyte n...
